Guidance

I am trying to make a decision between two options. It seems very likely that my partner and I will be separating after 10 years together (got together at 15 years old), and I'm trying to figure out where to go from here. Do I move to a farm my oldest sister bought (which is what I was doing, or my younger sister has asked that I consider coming and living with her for a while and then stay in the city she lives in. Trying to figure out what would give me the most opportunities in life. 

The background is that for about a year and a half, my family and I came up with the idea of all living together on a farm, so my oldest sister bought some land in a small, remote country town and invited us to come and build on it ourselves if we wanted to. I didn't want to pass up the opportunity and told my partner this is something that i wanted to do and that he had to decide if this was a life he wanted but i was going either way as it didn't want to resent him for making me stay (we have be very disconnected over the last few years and have had a few problems, we just don't seem as happy as we used to), i know he is not going to go and that it is not something that he wants, he just hasn't told me yet but i have come to terms with that.

So my whole family decided to go, but just recently my younger sister has decided not to go as her husband is reenlisting in the Army, and she has asked me if I would consider moving in with her for a little while. I know moving there would give me a lot more opportunities, as there is a lot more work, and places to go and see, friends to make, and people to meet, as I will be single for the first time in my life. But I also like the idea of living in the country, but I'm not sure that there would be much for me there besides my family. 

I just don't want to regret my decision.
